An endoscopic study in anaesthetized patients. Airway obstruction with cricoids pressure and lateral tilt. Endoscopic and radiological studies, as well as patients who presented pulmonary aspiration, despite the use of the Sellick maneuver, have raised doubts on the usefulness of the technique.
Applying pressure on the cricoid cartilage increases the tonus of the upper esophageal sphincter 14but decreases the tonus of the lower esophageal sphincter 15suggesting the presence of mechanoreceptors in the pharynx that promote relaxation of this sphincter. Curr Opin Anaesthesiol, ; Cricoid pressurealso known as the Sellick manoeuvre or Sellick maneuveris a technique used in endotracheal brp to try to reduce the risk of regurgitation.
The technique involves the application of pressure to the cricoid cartilage at the neck, thus hurp the esophagus which passes directly behind it. Cricoid pressure displaces the esophagus: The objective of this configuration is to control the lateral movement of the cartilage 2.
Compression of the cricoid cartilage: current aspects
Besides, a considerable number of individuals identified the thyroid cartilage as the structure to be compressed. The effects on brochoscopy of applying pressure on the cricoid cartilage were evaluated by different authors, with conflicting results The force applied should be enough to prevent aspiration, but not high enough to cause obstruction of the airways or esophageal rupture in case of vomiting This association is a good option for the management of difficult airways in patients at risk for aspiration The BURP maneuver, when used in combination with Sellick maneuver, can hinder visualization of the glottis.
Minor events, such as nausea, vomiting, pain, or hemodynamic changes may occur during compression of the cricoid cartilage.
Placement of a nasogastric tube before anesthesia in high-risk patients for pulmonary aspiration, to drain liquid and gases present in the stomach, is a common practice. However, during vomiting, when esophageal pressure can be higher than 60 cmH 2 O, the maneuver should be discontinued due to the vurp of esophageal rupture.
Brock-Utne JG – Is cricoid bupr necessary? The study also evaluated the adequate force to be used according to those professionals.
Sellick maneuver is not a risk-free procedure. Assessing the force generated with the application of cricoid pressure. Besides, when not used properly, it can cause deformity of the cartilage, closure of the vocal cords, and difficulty ventilating.
The technique involves the application of backward pressure on the cricoid cartilage with a force of newtons  to occlude the esophaguspreventing aspiration of gastric contents during induction of anesthesia and in resuscitation of emergency burl when intubation is delayed or not possible.
Wilson NP – No pressure! According to the authors, cardiovascular changes were similar to those observed during tracheal intubation in awake patients. The proximal esophagus begins at the inferior portion of the cricoid cartilage. Can J Anaesth, ; However, other investigators have found that cricoid pressure does not increase budp rate of failed intubation.
Cricoid pressure – Wikipedia
Priebe Nurp – Cricoid pressure: When the Sellick maneuver is not applied properly, it can hinder intubation and ventilation Vanner e Pryle 19 observed that 30 N equivalent to 3 kg was the necessary force that should be applied on the cricoid cartilage to prevent regurgitation of NS in 10 cadavers with esophageal pressure of up to 55 cmH 2 O.
Since then, the maneuver janiobra been accepted by anesthesiologists as a fundamental step during the rapid ve technique. The technique is also important in possibly preventing insufflation of gas into the stomach.
However, this effect does not seem to cause gastroesophageal reflux Knowledge and performance amongst anaesthetic assistants. Roewer N – Can pulmonary aspiration of gastric contents be prevented by balloon occlusion of the cardia?

Canadian Journal of Anesthesia, 49 5 Besides, knowledge of the force to majiobra applied, acquired through training in mechanical models, decreased with time. Sellick described the importance of applying pressure in the cricoid cartilage during anesthesia induction to prevent regurgitation of gastric contents.
This is the only cartilaginous structure of the upper airways whose format represents a complete ring.
Applying force on the anterior aspect of the cricoid cartilage causes compression of the esophagus against the spine between the fifth and sixth cervical vertebrae C 5 and C 6as long as those structures are aligned in the axial plane.
Compression of the cricoid cartilage was initially described by Monro 1: The necessary force to compress 10 mL of air when the tip of the syringe is closed is approximately 30 N Fanning GL – The efficacy of cricoid pressure in preventing regurgitation of gastric contents.
Anaesth Intensive Care ; InFanning was the first author to study the intragastric pressure required to overcome the force generated by cricoid cartilage compression.
